What is the 2020th digit to the right of the decimal point in the decimal expansion of
?

a) 1
b) 2
c) 4
d) 5
e) 8

5

Step-by-step explanation:

The period is 6.

The first digit to the right is 4.

The second digit to the right is 2.

Third digit to to the right is 8.

Fourth digit to the right is 5.

Fifth digit to the right is 7.

Sixth digit to the right is 1.

Then it starts over again.

The seven digit is 4. (Keep in mind 7=6+1).

The eight digit is 2. (Keep in mind 8=6+2).

So on...

So you can find the digit by finding the remainder of the nth digit to the right divided by 6 (since the pattern repeats the same 6 digits each time).

2020=6(336)+4

So the remainder is 4 since 2020/6=336+4/6.

Since the remainder is 4:

"Fourth digit to the right is 5".

The answer is 5.

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
